income

(i) The term income has the same meaning as it does under section 643(b) and the regulations thereunder, except that income generally may not include any long-term capital gains. However, in conformance with the applicable state statute, income may be defined as or satisfied by a unitrust amount, or pursuant to a trustee's power to adjust between income and principal to fulfill the trustee's duty of impartiality, if the state statute both provides for a reasonable apportionment between the income and remainder beneficiaries of the total return of the trust and meets the requirements of 1.643(b)-1. In exercising a power to adjust, the trustee must allocate to principal, not to income, the proceeds from the sale or exchange of any assets contributed to the fund by any donor or purchased by the fund at least to the extent of the fair market value of those assets on the date of their contribution to the fund or of the purchase price of those assets purchased by the fund. This definition of income applies for taxable years beginning after January 2, 2004.
